Ariana Grande's One Love Manchester concert was a resounding success and featured everything from a surprise Liam Gallagher appearance to a Take That reunion when Robbie Williams joined his old bandmates on stage.

The 23-year-old popstar organised the concert to raise money for those affected by the suicide bombing at her Manchester Arena concert on Monday, May 22.

Ariana had just come off stage when an explosion rocked the foyer of the venue, killing 22 innocent people and injuring more than 100 others.

Organisers hope to raise at least £2m toward the We Love Manchester Emergency Fund. All the artists are performing for free while concert promoter Live Nation has underwritten the cost of the event.

'Broken' Ariana suspended her tour and returned home to the US to be comforted by her loved ones after 22 people were killed and 120 more were injured when a suicide bomber targeted crowds leaving her gig.

Some of the child victims of the bomb attack at Ariana’s Manchester Arena concert on May 22 were still wearing casts and bandages tonight, but nothing was going to stop them seeing the tribute concert.

Tens of thousands of children flocked to the pop concert – to shame the murderous hate mongers who want to blight their lives with fear.

One Love Manchester will be remembered as an "iconic concert", says impressed viewers
